Accuracy of Building Control drawings?

any drawing that has to be scaled from using a ruler is a joke.

 

Construction drawings with every single measurement on them are mandatory. Once the builder has these he can then turn them into something close that can be built.

 

So the architect shouldn't have given his drawings to the Structural Engineer then?

Normally they ok as they get a cad drawing they can scale from. In any case whatever SE comes up with YOU need to double check reflects reality as built. Beam lengths etc

 

Again, never build from a scaled drawing and ruler.

As a designer/contractor we would never use the drawings supplied by an architect for detailed design.

We would see them as for aesthetics , function and planning only.

The whole thing gets redrawn with construction in mind, in more recent years in 3D which shows up anomalies.

 

Why?

Firstly it is how we think, and optimise a detailed design. Secondly we have seen so many errors. For example a chimney that is in 2 places at once (on 2 elevations),  roofs that don't line up. A stair in 2 positions at once so that it goes through a room.

A note saying 'for planning only' is often the get-out, but not always stated.

 

This is not such a big deal in a normal house as there isn't much to go wrong, and usually a good builder's common sense just sorts it. But not always.

 

The issue can be that the client commissions an Architect only to do the minimum, and so the drawings are not ready for anything else.

 

Shock horror...at uni, Architects are instructed to experiment, and that making it work is down the the Engineers and builders.
